Claims.

This invention relates in general to bottle lling machinery such as is used for filling bottles with carbonated beverages and more particularly to machinery of this class adapted to supply or 5 .till the bottle with several ingredients as, for example, with a Small supply of concentrated sirup and with suiiicient carbonated water to completely iill the bottle. Many beverages now on the market are made up of a certain proportion of concentrated Sirup and carbonated water. It is important that the Sirup and carbonated water be supplied to the bottles in proper proportions in order to make the beverage tasty and wholesome although the proportions of Sirup and carbonated water vary for various beverages.

In a well known type of automatic bottle lilling machinery a rotatable enclosed liquid receptacle is provided and carries a number of iilling heads and also a number of bottle holders, the 2o latter being automatically raised and lowered first to bring the bottles into cooperative relation to the filling heads for filling and to then move them away from the iilling heads as the bodily rotation of the bottle holders with the liquid receptacle carries them to the discharge means or turn-out chute associated with the machine. When the bottles are brought to the liller head they are first lled with the gas under pressure until the pressure in the bottle is the same as the pressure on the carbonated liquid in the receptacle. The carbonated liquid is then delivered into the gas iilled bottle with the result that all foaming and loss of liquid is avoided.

One oi the principal objects oi the present in- J vention is to provide, in a machine of this character, for the delivery to the bottle oi a measured amount of sirup and to (3o-ordinate the delivery oi the Sirup and the handling thereof with the automatic operations incident to the `lling of the bottle with gas pressure and with the carbonated liquid or carbonated water.

Another object resides in the provision of a machine of this character and having these advantages and capacities and which is simple and durable in construction, reliable and effective in operation, and easy and comparatively inexpensivo to manufacture.

A further object is to provide a machine of this character wherein the amount of sirup delivered to each bottle may be readily varied.

ther objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings', forming a part of this specification, and in which:

Referring to the drawings, it will be seen that there is shown an automatic bottle lling machine oi the type fully shown and described in Patent No. 1,166,520, granted January 4, 1916, to John E. Henes. This type of bottle lling machine has an hermetically sealed receptacle 1, in the lower portion of which a quantity of liquid is maintained at a constant level. Above the liquid and within the receptacle 1 a supply of gas under pressure is maintained. For these features and for the manner of supporting and automatically raising and lowering the bottle holders 2, reference is made to the patent referred to above, which contains a full disclosure of these features.

For the purpose of the present invention, it is suhicient to understand that the receptacle 1 is supported for rotation and is constantly rotated under the action of a Suitable power drive. The bottle holders 2 are constrained to rotate with the receptacle and are raised and lowered by individual fluid pressure motors, each having a control valve regulated in its action automatieally by means of xed pins or rollers positioned to open and close the valves at the proper time. The parts are arranged to eleiii) vate the bottle holders just after they have passed the loading station and to lower the bottle holders before they reach the discharge station or turn-out chute.

As in the patent above referred to, the receptacle 1 is provided around its periphery with a number of lling heads designated generally at 5. The construction of these lling heads differs in some respects from that of the lling heads in the patent above mentioned in order to adapt them to dispense sirup as well as carbonated water and to dispense the sirup in measured quantities. Each filling head 5 has a body 6 coupled or connected as at 7 to the liquid receptacle 1. A filling siphon is provided on each filling head and has a long bottle filling leg 8 in the form of a tube, the lower end of which is provided with a collar 9 formed with a valve seat and the upper end of which is threadedly connected with the body of the filling head and in free and open communication with a liquid supply passage 10. The inner end of this passage 10 lis connected to the angularly formed short leg 11 of the Siphon, the lower end of this short leg 11 being immersed in the liquid in the receptacle 1. A valve 12 is arranged lto coact with the seat on the collar 9 (see Figure 2), and is carried at the lower end of an elongated stem 13, much smaller in cross section than the bore of the tube 8 and adjustably connected at its upper end to the center of a diaphragm or pressure responsive member 14, the periphery of which is held against an annular seat or shoulder 15 in a pressure chamber 16 by means of a ring nut 17. Below the diaphragm 14 the chamber 16 is in open communication with the liquid supply passage l() by virtue of the provision of an axial opening or passage 10 provided in the body of the lling head and connecting the passage 10 with the lower portion of the chamber 16 and with the upper end of the filling tube 8 of the Siphon.` Since the liquid in the receptacle 1 is under pressure and since the diaphragm 14 is subjected to the action of this liquid under pressure and iiexed upwardly thereby, the Valve 12 is normally closed.

A bottle sealing cap, designated generally at 20, is slidably fitted on the filling tube 8 of the siphon although prevented from falling off of the tube by the collar 9. A gasket or sealing ring 21 is embodied in this cap 20 and is engageable with the upper end of the bottle as shown in Figures 1 and 2 to provide a seal between the cap and the bottle. For the purpose of providing a seal between the cap 20 and the filling head, when the cap is in its raised position, the portion of the filling head surrounding the upper end of the filling tube 8 is provided with a gasket or sealing ring 22 with which a neck 20 of the sealing cap engages.

The initial operation in filling the bottle conn sists in building up pressure therein until the pressure in the bottle equals the pressure acting on the liquid in the receptacle 1 and the means employed for carrying out this purpose includes a pressure supply passage 25 leading horizontally through the filling head, the inner end of the passage 25 being in open communication with the interior of the receptacle 1 and the outer end of the passage 25 terminating at a valve seat 26 formed on the outer end portion of the lling head. A pressure transfer passage 27 is also provided through the filling head and extends from the face of the valve seat 26 inwardly and downwardly through the filling head to a series of passages 28 located within the gasket ring 22 and adapted to discharge pressure down throughthe sealing cap 2i) and into the bottle. The points at which the passages 25 and 27 eX- tend through the valve seat 26 are spaced from each other as shown in Figure 4 and their communication is regulated by a disc valve 29 supported at its center for rotary movement on the lling head by means of a pivot bolt 30 and urged against the seat 26 by a spring 31 encircling the outer end of the bolt. A nut 32 is threaded on the outer end of the bolt and engages the outer end ci the spring to tension the same properly. An anti-iriction device 34 may be interposed between the inner end of the spring 41 and the adjacent portion of the valve 29. The inner face of the disc valve 29 is recessed to receive a washer 35 and both the valve and washer 35 have diametrically opposite arcuate slots designated at 37 and 38. Except for the slots 37 and 38 the washer 35 is imperforate. The slot 38 of the valve is designed to form a bridge or connection between the passages 25 and 27 in one position of the valve so that pressure may be carried from the pressure supply passage 25 to the pressure transfer passage 27. In another posin tion of the valve the slot 38 similarly connects the transfer passage 27 with a vent 39 leading from the surface of the valve seat 26 to the atmosphere. The valve 29 is automatically shift ed by means of cams 40 and 41 provided thereon and respectively and successively cooperable with pins or rollers 42 and 43 carried by the xed structure cf the machine or by stationary posts 44 mounted adjacent the machine. posts 44 and the pins carried thereby are so positioned as to operate the valves or the filling heads at the proper time in the cycle of the operation.

After a bottle holder 2 elevates a bottle to the position shown in Figures 1 and 2, wherein a seal is provided between the cap 20 and the bottle and between the cap 20 and the llng head, the valve 29 is shifted to the position in which the slot 39 connects or bridges the passages 25 i and 27. As a consequence, the pressure in the interior of the receptacle 1 above the liquid iiows through the passage 25, across the slot 33 and down through the passages 27 and 28 and through the opening of the cap 20 into the interior of the bottle. When the pressure in the interior of the bottle has reached the same value as the pressure in the receptacle 1 above the liquid it is desirable to open the valve 12 so that the liquid in the receptacle will be siphoned into the bot- 1c tle. For this purpose the pressure transfer paf'- sage 27 connects with a branch passage 45 which extends up through the filling head and through the passage of a connecting member 46 and leads into the interior of the pressure chamber 16 above the diaphragm 14 thereof. As a consequence of this arrangement, when the pressure is building up in the bottle it is building up in the chamber 16 above the diaphragm i4 and when the pressure in the chamber 16 rises to the same value as the pressure in the receptacle 1, the pressures on the opposite sides of the diaphragm 14 are balanced and the weight of the valve 12 and its stem 13 as well as the weight of the diaphragm causes the diaphragm to downwardly and consequently results in the valve 12 moving downwardly away from the seat of the collar 9 thereby permitting the liquid to flow through the siphon and into the bottle. This iiow continues until the level of liquid in the bot- The i chamber and the connecting member. 4U

tle rises to the level of the liquid in the receptacle 1. These levels are so regulated as to ll the bottle to the desired extent. The operations are so timed that shortly after the bottle is completely lled the valve 29 is shifted by Virtue of the engagement of its cam 41 with a roller or pin 43 to bring a blank or imperforate portion of the valve over the pressure supply passage 25 and bring the slot 38 in bridging or connecting relation to the pressure transfer passage 27 and vent 39. When the valve is so positioned the pressure above the diaphragm 14 is exhausted and consequently the pressure below the diaphragm iiexes it upwardly and closes the valve thereby preventing ow of the liquid when the bottle is lowered away from the lling head.

With the present invention it is proposed to deliver into the bottle a measured amount or sir'up or other liquid simultaneously with the filling of the bottle with the carbonated water. To effeet this result the connecting member 46 is screwed or otherwise fastened to the filling head and has liquid and gas tight connection therewith by virtue of the interpositioning between the coupling and the lling head of a washer or gasket 47. Above the connecting member, a sirup measuring chamber 48 is disposed and is secured in position by a conventional type of coupling 50 swiveled on the connecting member 46 and having the conventional mutilated or arcuate anges 51 cooperable with the usual tapered mutilated flanges 52 on the lower end of the measuring chamber 48 so that upon appropriate manipulation of the coupling member 50, the measuring chamber will be forced into iiuid tight connection with the connecting member 46, this fluid tight connection being established by means of a gasket 53 interposed between the measuring A diaphragm or pressure responsive member 55 is clamped between the upper end of the measuring chamber and a pressure cylinder 56 secured to the measuring chamber by means of screws 57 or other suitable fastening means.

Sirup is supplied from any suitable source, such as an elevated supply tank (not shown), through a sirup supply pipe 60 (see Figure 1), the supply pipe 60 connecting through a swivel coupling 61 with a pipe 62 extending down through a stuffing box 62 provided on the top of the rotary receptacle l and connected to a supply manifold 63 positioned within the receptacle. Branch pipes 64 lead from the manifold 63 to each iilling head, each branch pipe being connected with a Sirup supply passage 65 formed in and extending lengthwise of its iilling head. Each sirup supply passage 65 terminates at the surface of the valve seat 26 as shown in Figure 4 and in spaced relation to a sirup transfer passage 66 also leading from the surface of the valve seat 26 and extending through the iilling head to a passage 67 in the connecting member 46, the passage 67 discharging into the open lower end of the measchamber. The passages 66 and 67 are in effect a single continuous passage serving both as an inlet and discharge passage for the measuring chamber. A sirup discharge or delivery passage 68 leads from the surface of the valve seat 26 at an angle through the iilling head and communicates through the passage 10 at a point just above the filling tube 8. The arcuate slot 37 of the valve 29 operates in one position of the valve to bridge or connect the sirup supply passage 65 and sirup transfer passage 66 thereby supplying the sirup to the measuring chamber 48. In the other position of the valve the supply passage 65 is blocked and the slot 37 bridges or connects the transfer passage 66 with the discharge passage 68 thereby permitting the sirup to flow from the measuring chamber through the passages 67, 66 and slot 37 to the discharge passage 68 and thence through the lling leg 8 into the bottle.

En order to determine or measure the amount of sirup dispensed into each bottle the diaphragm 55 has a pin 70 secured to the center of a cup 7l which is also fastened to the upper face of the diaphragm at its center. The pin 7() is slidably fitted in an axial bore or opening formed in an adjustable stop sleeve 72, the sleeve 72 being slidably and rotatably tted in a guide 73 provided therefor in the upper end of the cylinder 56. A stumng box 74 is provided between the lower end of the guide 73 and the stop sleeve 72. The periphery of the sleeve 72 is formed with a series of recesses or blind holes 75 arranged spirally around and along the stop sleeve and adapted to selectively cooperate with a spring projected pin or detent 76 mounted on the cylinder 56 and protectlble across the opening of' the guide 73 and into engagement or intertting relation with any one of the recesses 75 that may be alined therewith. The spiral arra ..gement of the recesses 75 about the sleeve 72 is such that for any angular adjustment of the sleeve only one of the recesses 75 is in vertical alinement with the pin 'Z6 and consequently the pin 76 will snap into only one of these recesses. For turning the sleeve '72 while permitting it to slide freely through its guide 73 until one of its recesses is engaged with the pin 76, a flanged collar 77 is rotatably supported on the reduced upper end of the cylinder 56 and is constrained to rotary movement by means of set screws 78 threaded through the collar and having plane or smooth inner ends fitted in an annular groove formed in the reduced upper end o the cylinder. Integral with the collar 77 is an inwardly projecting fin or key 79 which is slidably tted in a lengthwise groove 80 formed in the sleeve. By turning the collar 77 or the sleeve 72 connected thereto, any one of the recesses 75 may be brought into vertical alinement with the pin 76. As the recesses 75 are not only angularly spaced around the sleeve 72 but also spaced axially therealong, they, together with the pin 76, provide means for releasably locking the stop sleeve 72 in various adjustments with respect to the diaphragm and consequently determine the limit of upward fiexure or" the diaphragm. The Volume of the measuring chamber depends upon the amount of the upward iiexure of the diaphragm and this in turn is determined by the position of the stop 72 which engages a boss 71 on the cup 71 to limit the upward ilexure of the diaphragm. Further, the adjustment of the stop 72 is determined by the angular adjustment of the collar 77 which, in turn, vdetermines whch one of the recesses 75 is positioned to engage the locking pin 76. The parts are so proportioned and are of such size that the volume of the mixing chamber is made to correspond to ounces and quarter ounces and any volume may be selected by turning the collar 77 until the appropriate scale marking 81 thereon is alined with an index marking 82 on the cylinder (see Figure l) When the valve 29 is positioned to permit illing of the measuring chamber, in which position the slot 37 bridges the passages 65 and 66, the sirup flows into the measuring chamber under its own head, that is, under the action of gravity. 1

And the diaphragm 55 freely flexes upwardly since at this time the pressure cylinder 56 immediately above the diaphragm is vented to the atmosphere. In this connection it will be noted that the pressure cylinder 56 connects by a passage in the wall of the cylinder with a passage 86 formed on the measuring chamber 48 and the passage 86 in turn connects with a passage 87 formed in the connecting member 46, having open communication with the pressure chamber 16 above the diaphragm 14. As a consequence, when the cylinder 16 above the diaphragm is vented the pressure cylinder 55 is vented and such venting occurs when the valve 29 is positioned so that its slot 37 bridges the passages 65 and 66 for at such time the slot 38 is necessarily so positioned as to bridge the passage 27 and the vent 39. On the other hand, when the slot 37 is positioned to bridge or connect the passages 66 and 68 and thus connect the measuring chamber with the bottle filling leg 8, the slot 38 bridges or connects the passages 25 and 27 thus supplying pressure to the chamber i6 above the diaphragm 14 and also to the cylinder 56 above the diaphragm 55. The pressure thus supplied to the cylinder 56 forces the diaphragm 55 downwardly and displaces the sirup from the measuring chamber into the bottle.

In Figure 8 a slightly modified form of adjustable slot is shown'. As illustrated in this figure the cylinder 56 has a removable cap 90 closing its upper1 end. Integral with the cap 90 is an internally threaded sleeve or nut 91. The sleeve stop corresponding to stop 72 in the other embodiment of the invention is here designated at 72 and has an external screw thread 93 for a portion of its length, the screw thread 93 intermeshing with the threads of the sleeve 91. The sleeve stop 72 slidably receives the pin 70 of the diaphragm as in the other embodiment of the invention and there is also a stuffing box 74 between the sleeve 91 and the stop 72. With this form, however, the flanged collar is omitted and the indicia designated at 81 is mounted directly on the stop 72 and coacts with a fixed index mark 82 applied or formed on the sleeve 91.

:In operation, the bottles are placed on the holders 2 by an attendant at the loading station in accordance with the usual practice, or they may be placed in any manner on these holders. When the bottles are placed on the holders 2, the latter are lowered but after leaving the loading station the bottle holders are elevated in a manner described in the patent above referred to. When the bottle holders have moved the bottle up into the position shown in Figures 1 and 2 the pins 42 coact with the cams 40 to shift the valve 29 to the position wherein its slots 37 and 38 bridge or connect the passages 25 and 27 and 66 and 68, respectively. As a result, the pressure in the receptacle 1 above the liquid ows into the bottle and also into the chamber 16 above the diaphragm 14 and up into the cylinder 56 above the diaphragm 55. The pressure in the cylinder 56 tends to flex the diaphragm 55 downwardly and consequently to displace the sirup from the measuring chamber down through the passages 67, 66 and through the slots 37 into the passage 68 and thence through passage 16 and tube 8 into the bottle. As soon as the pressure in the chamber 16 rises to a point where it equals the pressure in the receptacle 1, the valve 12 is opened under the action of gravity and both the sirup and the carbonated liquid fiow into the bottle. After the filling operation has been completed the pins 43 coact with the cams 4l to shift the valves 29 back to the position where the pressure supply passage 25 and sirup discharge passage 68 are blocked and wherein the slots 37 and 38 bridge or connect the sirup supply passage 65 and sirup transfer passage 66 and pressure transfer passage 27 and vent 29, respectively. As a consequence, the pressure is bled from the chamber 16 and the cylinder 56 so that the valve l2 closes and the measuring chamber lls with sirup so as to be ready for the next lling operation. After the Valves 29 have been shifted in the manner just described, the bottle holders 2 are lowered and the bottles are carried out of the machine at the discharge station in the manner described in the patent above referred to. The amount of sirup delivered to each bottle is determined by adjusting the stops 72 or 72 as the case may be. and thus limiting the extent to which the diaphragm 55 may flex upwardly.
